MARTIN LAERNOES AND JOHN DUN N, OF STREATOR, ILLINOIS, ASSIGNORS TO THE VULCAN DETINNING PORATION OF NEW JERSEY.

COMPANY, OF NEW YORK, N. Y., A COR- MACHINE FOR COMPRESSING DETINNED OR OTHER SCRAPS.

SPECIFICATION forming part of Letters Patent N 0. 737,424, dated August 25, 1903-. Application filed Tnuary 10, 1903. Serial No. 138,511. (No model.)

To all whom it may concern:

Be it known that we, MARTIN LAERNOES, acitizen of the Kingdom of the Netherlands, and JOHN DUNN, a citizen of the United States of America, both residing in Streator, in the county of Lasalle and State of Illinois, have invented certain new and useful Improvements in Machines for Compressing Detinned or other Scraps, of which the fol- IO lowing is a specification.

Tin scraps obtained in the manufacture of tin cans and from other sources, as well as waste pieces of tin, are detinned by dissolving the tin on the scraps by an electric ourrent. The remaining iron and steel scraps are then transferred to a machine for compressing the same into compact bundles or blocks of rectangular or other shape, which are shipped to the iron and steel works for being melted and utilized.

The object of this invention is to furnish a machine for compressing detinned or other scraps in a compact effective manner, which machine is operated by steam or air in the nature of the well-known steam-hammer, in connection with a number of receivers which are filled with scrap, successively subjected to the action of a powerplunger, so that the scraps in the boxes are o compressed into small blocks, said blocks being then transferred by suitable mechanism to a conveyer ready for shipment; and the invention consists of a machine for compressing detinned and other scraps, which comprises a plurality of receiving-boxes that are arranged on a stationary foundation-plate that is provided with an opening, an anvil arranged below said opening, a vertically-reciprocating plunger located vertically above 0 the opening in said foundation-plate, means for imparting a step-by-step motion to said receiving-boxes, and means for reciprocating the anvil so as to transfer the compressed scraps to a suitable conveying mechanism.

5 The invention consists further. 01" certain details of construction and combinations of parts, which will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a side elevation of our machine or compressing detinned and other scraps. Fig. 2 is an end elevation of the same. Fig.

3 is a vertical transverse section on line 3 3, Fig. 1. Fig. 4 is a plan View partly in horizontal section on line 4 4, Fig. 1; and Fig. 5 is a perspective view of the reciprocating anvil.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents a foundationplate of our improved machine for compressing detinned tin and other scraps. The foundation-plateA is preferably made in the shape of a disk and of suflicient strength to support a number of receiving-boxes B, which are of rectangular, round, or other cross-section and reinforced at their lower ends by exterior strengthening-straps b. Each receiving-box B is composed of two or four parts, which are provided with perforated ears or, that are connected by means of fastening-bolts. The receiving-boxes may also be made of one piece, thereby doing away with bolts. They are made thicker at their lower ends, so as to resist the strain to which they are subjected when compressing the scraps. The upper ends are rounded oif or tapered at their inner edge, so as to facilitate the feeding of the scraps into the same from a platform P, which surrounds the receiving-boxes B. A number of receiving boxes is arranged on the foundation-plate A, six being shown in the drawings, which are arranged equidistantly from each other. These six receiving-boxes are connected near their lower ends by a ringshaped frame B',which is provided with openings corresponding in shape and size to that of the receiving-boxes and so as to embrace said boxes. At the outer circumference of the frame B are arranged flanges b, which 0 are equidistantly connected by bolts 6 The inner circumference of the ring-shaped frame B is guided on antifriction-rollers f, which are pivoted to stationary rings f, as shown in Fig. 4, said rings f being firmly attached 5 by strapsf to a pair of upright standards S, so that the ring-shaped plate B maybe turned along said rollers around the vertical central axis of the rings f and the foundation-plate A. A step-by-step or intermittent rotary mo- :00

tion is imparted to the ring-shaped frame B by a hook-shaped lever O, which is pivoted to a collar 0 on the piston-rod D of the piston of a horizontal steam or air cylinder D, that is provided with suitable inlet and outlet valves, (not shown,) which are operated at the proper time. The hook-shaped end of the lever O is moved along the circumference of the frame B and engages one of the bolts b of the same, so as to move the frame and the receiving-boxes intermittently through the distance of one-sixth of the circumference of the frame B as soon as the motor fluid is admitted to the cylinder D. By the outward motion of the piston and piston-rod of the cylinder D the hook-shaped lever C is moved again along the circumference of the frame B into engagement with the next bolt 19 on the ring-shaped frame B, and so on A secondpair of upright standards S is arranged outside of the foundation-plate A, the upper ends of said upright standards S and S being connected with a strong top plate E, which is firmly held in position by suitable screw-nuts e. The lower ends of the standards S S are likewise connected with the per forated ears e of a bottom block E. The top plate E serves to support a vertical cylinder F, which is provided with suitable inlet and outlet valves and a suitable lever mechanism for operating the same. To the lower end of the piston-rod F of the cylinder F is attached a plunger F the shape of which corresponds exactly to the cross-section of the receiving-boxes, so as to fit snugly to the same. Between the plunger F and the lower end or head of the cylinder F are interposed a number of stout cushioning-springs G, which are retained between a stationary plate g and a sliding plate g, the latter being arranged immediately adjacent to the plunger, said sliding plate being guided in stationary bra kets or hangers 9 that are attached to the lower head of the cylinder F. After one ofthe receiving-boxes B charged with scrap is placed below the plunger by the spring-actuated hook-shaped lever G the plunger is operated by intermittently admitting steam or air to the vertical cylinder F, so as to produce a series of blows in quick succession for compressing the scraps in the receiving-box until they are compacted into a square bundle or block in the opening 0 of the foundation-plate A. The foundation -plate is made thick enough for this purpose. As the scrap is gradually compressed the strokes of the plunger are repeated at greater intervals, the force of the plunger being taken up at the end of each upstroke by the cushioning-springs, so as to facilitate the working of the plunger and cylinder and prevent injury to the latter.

During the compression of the scraps in the receiving-box B, that is located at the time below the plunger F an anvil 1-1 is located below the opening 0 in the foundation-plate A, as shown in Fig. 8, said auvzl be-1.1g pro vided with a recessed extension 71 corresponding approximately with the cross-section of the i'eceivingbox, so that the scrap when compacted can be transferred from the opening 0 of the foundation-plate A into the recessed portion h of the anvil. A final stroke of the plunger transfers then the bundle or block bodily from the opening 0 in the foundation-plate A into a recess h of a horizontallyreciprocating anvil H after the same has been withdrawn sidewise. This is accomplished by a third cylinder 1, which is operated by means of inlet and outlet valves, and the piston-rod t' of which is connected with the solid portion of the anvil H. The anvil is shown in detail in Fig. 5, the recessed end of the same being somewhat larger than the block into which the scraps have been compacted, so as to freely receive the blocks when the anvil is withdrawn from and the recess it placed under the opening 0 in the foundationplate A. The forward feeding of the block of compressed scraps is accomplished by the forward motion of the anvil, so that the block is delivered to an inclined chute L, which is attached to the anvil-supporting block E, as shown in Fig. 3. From this chute the package is either conducted directly to the car, by

which it is sent back to the mill for remelting,or to a suitable conveyer to the place where they are stored for shipment. As soon as the anvil is replaced below the opening 0 of the foundation-plate the cylinder D, which imparts step-by-step or intermittent rotary motion to the receiving-boxes, is again operated by the attendant and the entire set of receivingboxes, which are charged with scraps, are placed below the vertically-reciprocating plunger and the scrap in the same compressed,after which the operation of withdrawing the anvil and discharging the compressed scrap-block is repeated, as before described. These operations are repeated, the boxes being charged with scrap from the platform as they are rotated, so that one receiving-box after the other is placed below the plunger and over the opening in the foundation-plate closed by the anvil, whereby the scrap is compressed in the same. The operation of the machine is controlled by the three power-cylinders, the first cylinder bringing the charged receiving -boxes one after the other below the plunger, the second operating the plunger, so as to compact the scraps in the receiving-boxes, and the third actuating the anvil at the proper time, so as to receive the blocks and discharge them into the conveying-chute. By arranging the levers and valves of these three cylinders one attendant may operate the whole machine for compressing the detinned or other scraps, which are then shipped to the mill for further treatment.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1.
